dpAutoRigSystem vs Mixos Mold

dpAutoRigSystem is a free, open-source Python script for automating rigging in Maya. Its modular, multilingual, object-oriented design lets users assemble components into rigs. The documented process uses guides as rig blueprints, then parents them, sets rig attributes, adjusts controller shapes, skins the model, and prepares it for animation. A rebuilding feature supports updates to an existing rig. Skinning tools can create skinCluster nodes and change joint influences on selected geometry. Skin weights can be copied by closest-point or UV-space methods, or exported and imported as JSON files. Installation involves placing the dpAutoRigSystem folder in Maya’s scripts directory or another MAYA_PATH, then launching it with Python in Maya’s Script Editor. It runs with Maya on Linux, macOS, and Windows. The project says it was created to help users make rigs themselves, is GPL-2.0 licensed, and links to a wiki for documentation; maintainers invite questions, suggestions, and comments.

Mixos Mold is browser-based 3D sculpting software for shaping organic forms with GPU sculpting and pressure-sensitive brushes. Its toolset includes subdivision, dynamic topology, masking, symmetry, stamp alphas, brush presets, and remeshing. Users can import OBJ, FBX, or GLB models, unwrap a sculpt, and send it to Mixos Paint for layered PBR texturing. Mold runs without installation in a WebGPU-capable browser; desktop browsers listed are Chrome, Edge, Firefox, Brave, and Safari 26 or later. It also runs on iPad and Android in compatible browsers, and is included in the free Mixos iOS app for iOS 26 or later. Sculpting and saving to a library are free, but exporting finished meshes as GLB, OBJ, or STL requires a paid plan or perpetual license. Pro costs $8.99/mo, Max costs $17.99/mo, and a perpetual license costs $99 once. Account-saved projects can be opened across devices after sign-in. The maker says editing runs locally in the browser, but provides no equivalent security audit or uptime guarantee.
